Internet quickly & randomly disconnects

[invincib1e]

It's something to do with my computer - the internet, router, and wireless card all work fine, with up to date drivers.  It does the same when I wire directly to the router.  I've used 2 different routers and modems, so it's not them either.

The internet will randomly disconnect, but only for a couple seconds.  It will reconnect again right away.  This wouldn't be a huge deal, but I'm a gamer, and it's very noticeable and frustrating.

My computer has also had this 'slowing problem', I'm not sure if they're related. Sometimes when the CPU usage will jump to 100% everything is in 'slow-motion'.  It's most noticeable when I'm listening to music, the music will slow down, like playing a record slower, for just a couple seconds.  Other slowing effects happen also.  This usually only happens when I have a downloading program running, but it didn't used to do that, and shouldn't. 

Has anyone else had this before? Any help would be greatly appreciated.

Yes.  My iBook works fine.  My PC (running XP Pro) only has this problem.
